Camera Control
The bridge board supports two camera control methods:
DEFAULT
Onboard I²C–UART Bridge
Camera is controlled through the onboard I²C-to-UART bridge routed to the IMX8M Plus host.
EXTERNAL
Onboard UART Header (J2)
Controls the camera from an external system via RS422.
| Designator | Functionality |
|---|---|
| R37, R41 | Presence of R37 & R41 enables I²C–UART bridge |
| R30, R32 | Presence of R30 & R32 enables RS422 control |
By default, R37 & R41 are only placed in the bridge board. To control through RS422, remove R37 & R41 and place at R30 & R32
Warning
Only one control method can be achieved at a time.
